Abstract
This chapter reviews a new formulation fully coupled three-dimensional buffeting analysis of long span cable-supported bridges. The formulation is a complete finite element approach and a pseudo-excitation method. Dynamic coupling between modes of vibration, interaction between bridge deck and towers and cables, and varying wind speed and structural properties along bridge deck and towers and cables can be taken into consideration using this formulation. This chapter closes with the discussion of Tsing Ma long suspension bridge in Hong Kong, in which the new formulation is validated through a comparison with Scanlan's method, and aeroelastic effects, multi-mode effects, inter-mode effects, interaction between bridge components are investigated.
